UNITED STATES WILLIAM L. REYNOLDS AND EDWIN E. SLUDER, OF ST. LOUIS, MISSOURI, ASSIGNOBS OF PART OF THEIR RIGHT TO WM. B. DEAN, CHARLES D. MOODY, AND SAMUEL S. BOYD, ALL OF SAME PLACE.

lMPROVEMENT lN SMELTlNG-FURNACES.

Specification forming part of Letters Patent No. 185., I 32, dated December 5, 1876; application filed March 28, 1876.

To all whom it may concern:

Be it known that we, WILLIAM L. REY- NOLDS and EDWIN E. SLUDER, both of St. Louis, Missouri, have invented a new and useful Improvement in Sinelting-Furnaces, of which the following is a full, clear, and exact description, reference being bad to the annexed drawing, making part of this specification, in whicb- Figure 1 is a longitudinal sectional elevation taken on the line 3 y of Fig. 2, and Fig. 2 a cross-sectional elevation taken on the line a a: of Fig. 1.

Like letters indicate like parts. The present invention relates more especially to furnaces for smelting copper and lead.

Referring to the annexed drawing, A represents a furnace embodying the present improvements. It is an open furnace, similar to what is known as a forge-fire. B represents the fire-place, and O the escape-flue. D D E represents the bottom of the furnace. It is preferably made circular in cross-section, as shown in Fig. 2. Un-

derneath the bottom is arranged a lire-place, F, which is provided with an escape-flue,f, leading, preferably, into the flue O. The fireplace F is also provided with suitable gratebarsf. The bottom E of the furnace is made detachable, so that it can be withdrawn, and, if desired, readily renewed. It can also be adjusted longitudinally by properly elevating the rear end.

' In operation, while the smelting is going on.

in the furnace A above, a lire is maintained in the fire-place F below. By this means the bottom of the furnace is kept warm, and the contents of the furnace prevented from chilling upon the furnace-bottom. By reason of the shape of the furnace-bottom the molten metal collects in the center, where it can be tapped. The bottom of the furnace being detachable, it can be renewed when worn or burned out. This furnace-bottom rests, by flanges a, upon ways I) projecting from the walls of the furnace, and is adapted to slide on these ways and to be drawn out at the front without disturbing the brick-work.

What we claim is- The combination of the furnace A, fire-place B, sliding bottom E, and tire-place F, substantially as described and shown.
